r.li.padrange: Calculates range of patch area size on a raster map

NAME

r.li.padrange - Calculates range of patch area size on a raster map

KEYWORDS

raster, landscape structure analysis, patch index

SYNOPSIS

r.li.padrange r.li.padrange help r.li.padrange map=name conf=string output=name [--overwrite] [--verbose] [--quiet] Flags: --overwrite Allow output files to overwrite existing files --verbose Verbose module output --quiet Quiet module output Parameters: map=name Name of input raster map conf=string Configuration file output=name Name for output raster map

DESCRIPTION

r.li.padrange (patch area distribution range) calculates as: with: amax: max patch area size amin: min patch area size
EXAMPLES
To calculate range of patch area size, using my_conf configuration file and saving results in my_out file run: r.li.padrange map=my_map conf=my_conf output=my_out
NOTES
Do not use absolute path names for output files. They are raster if moving window disposition was selected, otherwise they are in ~/.r.li/output folder. If input raster is not full of null values r.li.padrange returns a value >=0 that is PADcv. If input raster is full of null values r.li.padrange returns -1. If you want to have null values instead run r.null setnull=-1 map=my_map after index calculation.
